agreed - short term swaps have limited value and I now temper expectations doing them. long term listening is the ultimate decision point.the test that matters is a week of listening to both; which one do you not want to not stop listening to? which gets old? makes you forget you are listening to reproduced music?
OP- fwiw, have a friend with Chronosonic XVXs who prefers his MC611s to Dagostino Momentums.
